Wrong principal in request error on gss_accept_sec_context()

[Xie, Hugh]

* What do "hostname" and "hostname -f" say on each host?
The working on are using "host1.bankofamerica.com" the non working one has "host2.site123.baml.com". "hostname" and "hostname -f" returns same string on both hosts.

In the KRB5_CONFIG of both hosts, default_realm is set to COMMON.BANKOFAMERICA.COM And the domain_realm is config from above host_name = COMMON.BANKOFAMERICA.COM

* What OS are these hosts running?
The working host is running EL5, the non working host is running EL6

* What server application are you getting the error from?  If it's a custom application, what name was imported to create the verifier_cred_handle argument of gss_accept_sec_context?
The application is custom app running under python. If you meant acceptor_cred_handle, it is generated with the following with the following code:
maj_stat = gss_acquire_cred(&min_stat, GSS_C_NO_NAME, GSS_C_INDEFINITE,
                                    GSS_C_NO_OID_SET, GSS_C_BOTH, &state->server_creds, NULL, NULL);

* Did you recently re-key one of the hosts without retaining the old keytab?  (If so, run kinit again on the client to flush any old service
tickets.)
I did this multiple times already.

Unfortunately several things can cause this error in 1.11.  (In 1.13 we try harder to disambiguate.)  Information which might help:

* What do "hostname" and "hostname -f" say on each host?

* What OS are these hosts running?

* What server application are you getting the error from?  If it's a custom application, what name was imported to create the verifier_cred_handle argument of gss_accept_sec_context?

* Did you recently re-key one of the hosts without retaining the old keytab?  (If so, run kinit again on the client to flush any old service
tickets.)
